Building the Future on Sludge
Monday, March 30, 2009 2:56With one of the key areas of focus in China to improve efficiencies being buildings, and building materials, I found the Cleantech article Sludge-powered cement in China? particularly interesting.
Guangdong, China-based Guangzhou Heidelberg Yuexiu Cement said it began treating sludge this week at its RMB 70 million ($10.2 million) facility designed to turn the wastewater byproduct into a fuel for cement-making.
The company expects the technology to both reduce the coal needed to produce cement, as well as tackle the sludge problem in China.
Initially, I must admit that I experienced a bit of a gag reflex when I first read this article as I thought about the fact that buildings of sludge laden cement would result from this technology. However it did not take me long to look past that and realize that with millions of km of road being planned as part of the recent stimulus package this was a product with a bright future.
